Tome... I'm not familiar with using the CLI tools that come with Calibre... I use the GUI. Yes, you can change the metadata only. Since the Calibre GUI just drives the CLI tools, I expect you can do it at the CLI.

However, this person was asking about getting the m2m GUI working. I was just recommending an alternative GUI tool that would allow him to make changes to mobi metadata.

Once again, don't think I was putting down your great effort... it was the only game in town when you first donated it to the community and I used it quite a bit.

I am just happy that something better exists and something that is also updated.
